Development of High-Temperature Strain Gages

Description: From Introduction: "An improved high-temperature gage was needed, and in an attempt to fill this need an investigation was initiated in February 1954 in the Enameled Metals Laboratory at the National Bureau of Standards. The present Monograph constitutes a final summary on this program."

Preliminary Design of a Basic Radiation Effects Reactor (BRER)

Description: From Introduction: "Information has been accumulated about the property changes produced, but there are essentially no reliable quantitative data correlating property changes with the magnitude and energy distribution of the neutron fluxes responsible for the changes. The design of the Basic Radiation Effects Reactor (BRER) presented herein stems from the two main requirements: 1. a fairly high-level, high-energy neutron flux with minimal thermal neutron and gamma-ray background is desired; 2. … more

A Report on Some Attempts to Cast Centrifugally Fuel Elements of Small Diameter

Description: Report issued by the Argonne national Laboratory discussing centrifugal casting of thin uranium plates. The applicability of the centrifugal casting technique to the production of multiple castings of fuel pins of small diameter and of thin fuel plates was investigated. This report includes tables, illustrations, and photographs.

The Cold Pressing of Sinterable UO₂

Description: The intent of this work was to explore more fully the pressing of sinterable UO2 powders into cylindrical compacts in the hope that a more precise prediction of green density in terms of powder properties, pressure, and geometry could be evolved.

DAMAGE TO CONVENTIONAL AND SPECIAL TYPES OF RESIDENCES EXPOSED TO NUCLEAR EFFECTS

Description: Ten residential structures of wood, brick, lightweight reinforced concrete block, and lightweight precast concrete slabs were exposed in pairs to the effects of a nuclear device of approximately 30 kt yield, detonated atop a 500-ft tower. The houses represented various structural types, and two houses of each type were tested. One house was located at an anticipated overpressure at which collapse or major damage might be expected and the other was located at an anticipated overpressure at which… more

THE EIGHTFOLD WAY: A THEORY OF STRONG INTERACTION SYMMETRY

Description: A new model of the higher symmetry of elementary particles is introduced ln which the eight known baryons are treated as a supermultiplet, degenerate in the limit of unitary symmetry but split into isotopic spin multiplets by a symmetry-breaking term. The symmetry violation is sscribed phenomenologically to the mass differences. The baryons correspond to an eight-dimensional irreducible representation of the unitary group. The pion and K meson fit into a similar set of eight particles along wit… more

Periodic Intercalibration of Temperature Sensing Elements. Core I, Seed 2. Test Results (T-641303)

Description: Tests were conducted to determine the direction and magnitude of drift in core thermocouples, primary loop and pressurizer resistance thermometers, and the resistance thermometers in the secondary side of the boilers. The temperature sensing elements of the reactor coolant loops did not show any significant short-term error. The tests of the core thermocouples were not conclusive. Test data are included. (J.R.D.)

FEASIBILITY STUDY OF A NEW MASS FLOW SYSTEM. Quarterly Report No. 3 covering Period December 1, 1960 to February 28, 1961

Description: A mass flow measurement technique was devised which meets many requirements for mass flow measurement systems. In this technique. fluid is made to pass through a pivoted S-shaped tube. which tends to rotate due to the angular momentum of the fluid. A torque motor and torsion spring maintain zero displacement. the restoring force being a measure of the angular momentum, and density is measured by absorption of radiation passing through a window in the S tube. From the measured angular momentum a… more

Quarterly Status Report on LAMPRE Program for Period Ending February 20, 1961

Description: S>The LAMPRE-I project is summarized in terms of capsule development and production, sodium system, cover gas system, capsule charge, shielding, and fuel storage facility. The loading of the LAMPRE-I core was begun on January 20, 1961 with the sodium temperature set at 160 deg C. The reactor was brought to criticality on February 17, 1961. Operation of the Sodium Test Facility was continuous ex cept for 6 maintenance and inspection shutdowns resulting in 680 idle hours. The intermediate sodium … more

HYDRAULIC TESTS OF A PROTOTYPE HALLAM FUEL ELEMENT (SU-9) TO BE TESTED IN SRE

Description: Pressure-drop measurements were made across a mockup of a Hallam prototype fuel element in a test section installed in the Hallam Hydraulic Loop. The flow channel was identical to an SRE fuel channel and included simulated upper and lower plenums. The fuel element mockup was equipped with a Hallam-type variable orifice at the channel exit and a fixed orifice in the strainer basket at the bottom of the element. Tests were performed to determine the optimum size for the fixed orifice and the temp… more

OPERATIONAL INVESTIGATION OF NUCLEAR INSTRUMENTATION. Test Results T- 643725. Section 1

Description: A test was run to determine the capability of the nuclear instrumentation system to indicate reactor transient behavior and to test the linearity and alignment of all four channels. The response to a resctivity insertion was found to be linear in the range tested 5 x 10>s-/sup >> / 5 x 10>s-/ sup > /p Channel A showed the best aligmnent. (D. L.C.)
